DEVICE FOR HANDLING BROKEN ENDS.

To all whom it may concern:

Be it known that I, ABRAHAM G. SHI- DEED, a citizen of the Empire ofTurkey, residing at Lawrence, in the county of Essex and State ofMassachusetts, have invented certain new and useful Improvements inDevices for Handling Broken Ends, of which the following is aspecification.

My invention relates to devices for taking care of the broken ends ofroving, sliver or yarn in the various processes of textile manufacture.It can be used alone or with different attachments and on variousmachines wherein such roving, sliver or yarn passes through deliveryrolls.

In the accompanying drawings, I show different embodiments of myinvention and its application to various machines.

In the drawings, Figure 1 shows in perspective, my device attached to adrawing box such as is used in worsted spinning with portions of therolls, pulleys, spindles and fliers broken away to show the constructionFig. 2 is a sectional side view of such a drawing box with my deviceattached. Fig. 3 is a top view of the block by which my device isattached to the spindle bracket either alone or in connection withanother stop motion. Fig. 4 is a front view of a drawing box showing mypresent device applied to the delivery rolls of a drawing box inconnection with a stop motion for which I received Patent No. 885,875dated April 28, 1908. Fig. 5 shows my invention applied to the ordinarydrawing frame used in cotton spinning. Fig. 6 shows it applied to thedelivery end of a cotton card. Fig. 7 shows it applied to a slubbingmachine. Fig. 8 shows it applied to a cap spinning frame.

Referring to the first four figures which show my device applied to adrawing box, I will describe the construction. The purpose of a drawingbox is to twist the ends A of the sliver as they are delivered from thedrawing rolls G and H to form the roving K and to wind the roving uponthe bobbins B. The spindles C, C are actuated by pulleys E, E. Eachspindle C carries a flier F provided with eyes 10 and 11 and each is inthe form of a tube at its upper end through the sides of which is anopening 12. The bobbins B, B are loosely mounted upon the spindles C C,and rest upon friction washers L, which rest upon plates M fastened tolifter plate N. They could re- Specification of Letters Patent.

volve freely upon spindles C, C were it not for the friction of washersL. Each sliver end A is delivered by the rolls G and H and passesthrough the top of the spindle C out through the opening 12 and throughone of the eyes 10. From thence it is wound around the arm of the flierF and passes through the eye 11 onto the bobbin B. The bobbin B isrotated by the drag of the roving K coming from the arm of flier F, butat a slower speed than the flier on account of the drag of washer L,with the result that a twist is imparted to the roving and it is alsowound upon bobbin B. It is distributed evenly upon bobbin B by the riseand fall of lifter plate N. This is the washer drag system. The bottomof each spindle C rests in a suitable opening in a pulley E, each ofwhich is actuated through belts and pulleys of well known constructionby fast pulley O on shaft 40.

In the well known type of machine to which this device is applicable,the spindle is supported at the top by a spindle bracket 30 into whichsets the bearing cup 50 which can be passed over the top of the spindleC and pushed into the opening in the bracket and dropped into placetherein, thus detachably holding the spindle in place. Each spindlebracket 30 is attached to the fixed rail R of the usual construction.The lower delivery rolls H are usually fluted and are fixed to thedriving shaft 20. The up per delivery rolls G are pressed by springsagainst rolls H and are usually covered with leather or smooth cloth.These rolls G are driven by frictional contact with rolls H. Rolls H areusually of steel on their surfaces. In the case of a break in the rovingbetween the contact point of rolls G and H and the bobbin B, the dragupon the roving ceases and no more is drawn into the top of spindle O.Either one of two things must happen. Either the roving which is stillbeing delivered falls over the spindle bracket 30 and winds up upon thetop of the still revolving spindle C, in which case it will be takencare of by my Patent No. 885,875 referred to by stopping the machine, orif it does not fall over the spindle bracket, it will be picked up bythe upper leather covered ro-ll G to which it will adhere in preferenceto the steel covered roll H. The result is that it continues to winduntil noticed by the attendant. Thereby vgreat waste is caused.

My device comprises a spool 60 which, preferably has at both ends. ahead. 61 and is carried loosely by a spindle 62; Spool" 60' ispreferably covered with rough cloth, felt,

wire or other material 90, to which roving,

at 92: to ablock 65* and. bent at. one end to avoid driving roll H anddriving shaft 20;. so that it can come uprproximate' and? a little to:one side of roll G. It. has. a. slot 66- at this. end: in whiclr the endof spindle 62 is adaptecb to slide. Spindle. 62 is also thread ed at theend. to: receive anaadjusting nut. 150 by whichit. may be adjusted alongslot 66;. The other end. of. rocker arm. 64; is pivoted' to=a link 93which is also pivoted to a connecting arm 94. fixed" to a pivot shaft70;For each set. of drawingrolls G and IL I provide the above arrangementof!" spool 60; rocker arm 64;, link 98': and connectlng arm 9.4.

Thepivot shaft 70 is carried by bearings which may be attached: to anyconvenient part. of? the frame 7-1, 7.11 of the machine.

The arms 94 onev for each set of' drawing rolls5 arefiXed to this pivotshaft asstated.v

A trigger arm- 7 3- is also carried at a suitable point by pivot shaft70.. To counter balance the weight of spool 60' and arm 7 3', I providea counterweight arm 74 upon which is the counterweight 75 detachablyattached thereto by means of a set screw.

In this type of'machine, the belt is thrown from the fast pulley 0 tothe loose pulley P by a shipper'connection operated by a ban dle carriedby a shipper shaft 81. I fix a shipper arm 82 to the shipper shaft. 81and pivot to the shipper arm 82; a shipper rod 83' which is supported byand slides in bearings 84 and 85 fixed: to any convenient part of themachine. A collar 86 ofgreater length than the-throw of the shipper rod88 is adjustably attached: thereto by means of a set screw. Around theshipper rod 83 resting at one end against the bearing 84 and at. theother end against collar 86 is a spiral spring 87. vVhen the belt isbrought on the fast pulley O by handle 80 to start the machine; thespiral spring 87 is compressed and collar 86 is brought into suchposition that trigger arm 73 will be brought up by'the counterweight 75in front OfE'COll211"86 thus retaining it in that position. It will beseen that if trigger arm. 7-3 is depressed out of the way of collar 86,spiral spring 87 will expand carrying with. it. the collar 86, shipperrod 83 and shipper arm 82" and will throw the belt from the fast pingthe machine: If a bre'al': occursin: the

roving A at any point after it leaves the com .tact point between thedelivery rolls G and H, the. loose. end will. ordinarily fall over the'spindle bracket or else cling to leather :ooveredroll be carried aroundthere .by,. and wound thereon as described. This causesa great waste ofthe roving With my device, the operation is as follows'r Spool 60 ismaintained by weight 75 acting on rocking arm 64 in contact withdelivery roll G, at all times and is rotated by: frictionalcontacttherewith at al li times while roll Gr isrot atedi by roll Withdevice, when a break occur-s asillustrated in Fig. 2;.if the looseendispicked up by roll Gt it is carried along as shown by the dotted linesuntil it strikesithe pointof contact with my spool. 60:. As spool? 60-is covered with felt or other tenacious material 90,-the end is. picked.from. ro'll Gr and winds upon spool: 6 a. As I make-the diameter ofspool 60. relatively" very" much less: than the diameter of'roll G and!as% it is rotated by frie-- tionalz contact: with that: lie-1 1,. theroving rapidly" winds. up and forms bunch as shown in Fig. This bunchforces spooli 60 outward. to the position: shown by the dotted lines inFig. 2-. This outward movement rocks; rocker arm 64; thereby liftinglink: 93 which througlt connecting arm 94. rotates shaft 70 sufficientlyso that trigger arnr 73: is moved downward-f clear of collar 86. Thisreleases spring." 87 which actuates the shipper and stops the machineas? de scribed. When the machine is stopped, the broken. roving. isreadily pieced Theroving oni spool 60 maybe unwound tothe end,whichcanzbe united to theother broken end: thereby c voiding any wastewhatever, or it" may be broken, pieced and then the remnant removed.from the-speol thereby saving time.

In? Fig. 5 is shown the application of my rough skin sp'ools to' adrawing frame of a typecommon in: cott oni yarn: manufacture- Theroving; 1101 passes between the drawing gro-lls 1.02. and l03 whichareshown aslocated in three sets closet-ogether; It is immaterial %withwhat these rolls are covered providedit does not cling too tenaciouslyto-therov ing 1013 1:11 this case, I use rough skin spools 10 i and 105carried: loosely by spin dies: on ar'mslOG' and 107 which are pivotedrespectively 108- and 109. cated' that the cop spools 10% rest on thetop of'iiolls1i02' and: the bottom: spools 105 They are solofl-1fi9li8lCll in contactwithi the bottom rolls 103 by the pressure ofaweight 110 acting on arm: 1071. Thepivoti rod '7'0,ntrigger arm 73',shipper rod: 8 3 an'dicollar86 are'of the same I or similarzconstruction: to those used inthe drawingbox above described. Arm 1 06has aniearlilll an'diarm: 1:0? has an ea r 112 which engage;respectively the noses- 113 and 114* :fiXed-i to pivot shaft 7.0:: Itcan be readily seen that if the roving brealts between the rolls orbetween the rolls and the head 115, it will be picked up by some one ofthe drawing rolls 102 or 103 as shown by the dotted lines and carried asfar as one of my spools. When it reaches a spool, it will wind thereonand force it outward carrying its supporting arm 106 or 107. This actionoperating through the ear 111 and nose 113 or ear 112 and nose 114 willforce downward trigger arm 73 thus releasing collar 86 and operating theshipping rod 83 to stop the machine. In the same way, my device may beapplied to the delivery end of a carding machine as shown in Fig. 6. 120is the sliver, 121 the can, 122 the upper delivery roll and 123 thelower delivery roll. In this construction, my spool 124 is carried by apivot arm 125 which connects a suitable link 126 with an arm 94 carriedby pivot shaft 70. The collar 86, shipper rod 83 and trigger arm 7 3 areof the same construction as above described. The link 126 may carry aweight 127 to overbalance spool 124 and trigger arm 7 3. In thisconstruction, if the sliver breaks, it is almost certain to falldownward by gravity as shown in the dotted lines over the lower deliveryroll 123 from which it is picked up by spool 124.

In Fig. 7 I show my device applied to a slubber, roving machine, dandy,reducer, or speeder. The roving 130 is delivered by driving roll 131 andleather covered roll 132 to the flier 133. The spool and arm 64 are ofsubstantially the same construction as shown in the drawing box shown inFigs. 1 to 4 and are connected to the shipper rod in the same way.

My rough skinned spool can also be used to advantage in connection witha machine like a cap spinning frame such as shown in Fig. 8 or in factin connection with any spinning frame or other machine where it is notdesired to stop the whole machine when a single end breaks. In theconstruction shown in Fig. 8, the lower delivery rolls 140 are thedriving rolls while each pair of the upper rolls 141 are presseddownward by a spring 142 which bears on their shaft 143 between them. Ifan end 144 breaks and winds on one of these delivery rolls, it raisesthat end of their shaft which causes extra pressure on the other rolland therefore uneven work. In such machines, it is not desirable to stopthe whole machine when a single end breaks as there are so many endsthat such stopping would cause needless loss of production. It istherefore the custom to allow the end to wind on one of the deliveryrolls from which it is afterward stripped and the end broken between thefingers of the operative who then pieces the broken ends. In using myrough skinned spools in such a machine, I prefer to rest the upper spool146 in guides 145 as shown, whereby it is kept in contact with the upperdelivery roll 141 by gravity. The lower spool 147 is supported on eachend by a carrier 148 so shaped that it has a rear arm and a forwardlyprojecting sloping arm of such shape that the lower spool can be pulledout readily and replaced readily. These carriers are carried by suitablepivoted members 149 and are held upward by a suitable weight 150 asshown.

In the construction shown in Fig. 8, after an end breaks, it is pickedup by one of the spools 146 or 147 where it winds up without disturbingthe equilibrium of the paired delivery rolls or otherwise causingtrouble. When the operative is ready to strip, he breaks the end andstrips in the usual man ner afterward removing the spools, and removingthe waste end therefrom either by unwinding or otherwise stripping it.As the delivery rolls 140 and 141 are always kept clear by the roughskinned spools, it is never necessary for the operative to clear themand he can piece the broken ends first and then unwind or otherwisestrip the spool.

My invention can be used upon almost every machine in the drawing roomand on some in the combing room. In fact it can be used upon any machinewhich delivers sliver or roving.

What I claim as my invention and desire to cover by Letters Patent is Ina stop motion for drawing boxes, a plurality of delivery rolls, aplurality of spools each covered with tenacious material and each socarried by a rocker arm as to be in frictional contact with one of thedelivery rolls, said rocker arms which are each pivoted to the frame ofthe machine, a pivot shaft, a lurality of arms fixed thereto eachconnected with a rocker arm, a trigger arm carried by the pivot shaft, aspring actuated shipper rod, and a collar carried thereby at such apoint as to engage the trigger arm.

In testimony whereof 1 hereto affix my signature in presence of twowitnesses.
